Back, Map, More, and Avoid
These buttons have common functions across all three
Detailed Traffic Event screens.

selected detailed traffic event.

If selected, the Map Traffic Event Icon screen displays.
Map Traffic Event Icon with Back Screen
Scroll to the new traffic ICON, and the INFO button
displays for that traffic event. Press INFO and the
detailed traffic event screen displays. Press the NAV
hard key to go back to the Full Map screen.
More: Press to display more of the traffic event
description, if the whole event does not fit in the given
display.
Avoid: This button is used to avoid the location of an
event on the route. If selected, a new route is calculated
and the related traffic event is avoided. After the new
route has been calculated, the navigation system
goes to the full map screen and shows the new route.
Traffic Voice Prompts
The traffic voice prompts are part of the current
navigation voice prompts. If the navigation voice prompts
are turned off, all traffic prompts are also turned off.
If the voice prompts are on, whenever an Alert for
Approaching Traffic or Alert if Better route Available is
displayed, the system gives the related voice prompt.
The content of the voice prompt depends on actual
traffic event data.
The RPT (Repeat) hard key is for navigation traffic
maneuvers only. It is not used to repeat traffic prompts.
During a traffic voice prompt, if RPT is pressed, the
current prompt playback cancels.
Anything that cancels the Alert for Approaching Traffic,
also cancels the related voice prompt.
Traffic prompts are disabled during OnStar
Recognition activity.
